Summary
This case report details a rare primary pineal embryonal carcinoma in a middle-aged man. Despite aggressive treatment, the tumor recurred and disseminated, leading to patient death.
Area of Science:
- Neuro-oncology
- Pathology
Background:
- Primary pineal embryonal carcinoma is an extremely rare germ cell tumor.
- It predominantly affects younger individuals, making its occurrence in middle-aged adults highly unusual.
Observation:
- A 42-year-old male presented with headache, nausea, and Parinaud's sign, indicative of a pineal region mass.
- Imaging revealed a tumor, surgically debulked, and initially suspected as a germ cell tumor, later confirmed as pure embryonal carcinoma.
Findings:
- The patient underwent chemotherapy (PE regimen) and craniospinal irradiation, achieving initial complete remission.
- Despite salvage therapies including re-operation and radiosurgery, the tumor recurred and disseminated, ultimately causing fatal intracranial hemorrhage.
Implications:
- This case highlights the aggressive nature and poor prognosis of pure primary pineal embryonal carcinoma, even in older patients.
- It underscores the need for further research into optimal treatment strategies for this rare entity, particularly in non-pediatric populations.
